Shark DuoClean Slim NV201vacuum cleaner

About

The Shark DuoClean Slim NV201 is part of the Vacuum cleaner
test program at Consumer Reports. In our lab tests, Upright vacuum
models like the DuoClean Slim NV201 are rated on multiple criteria, such as those listed below.

Carpet: Indicates how much embedded talc and sand a vacuum lifted from a medium-pile carpet.

Bare floors: Shows how well a vacuum picked up sand without dispersing it on bare floors.

Features

Brush on/off
Brush on/offAn on/off switch for the rotating brush lets you stop the brush from rotating when using tools or cleaning bare floors. This helps eliminate scattered dirt on bare floors and reduces the risk of injury if the vacuum tips over during use. It also reduces the risk of damaging a carpet or the finish of a bare floor if the vacuum sits in place at the low-height setting.

No

Easy on/off
Easy on/offA switch that's located on the handle or where your foot can activate it is more convenient than one on the body of the vacuum.

No

Manual-pile adjust
Manual-pile adjustLets you adjust the height of the machine to a carpet's pile height to allow for easy movement and thorough cleaning. Adjustments are automatic on some models, but we prefer the more precise manual control afforded by some models.

No

Accepts tools
Accepts toolsHas a hose to which you can attach tools.

Yes

Suction control
Suction controlThis feature reduces the flow of air through the hose, which can be helpful when cleaning upholstery and curtains.

Yes

Retractable cord
Retractable cordA feature that's common in canisters, not uprights, a retractable cord is one you can rewind via a slight tug or a push button.

No

Full-bag/bin indicator
Full-bag/bin indicatorSome models have a feature alerting the user when the dust bag or container is full, which impairs the vacuum's ability to clean. Some bagless models simply have a clear bin, letting you see when the vacuum is full. Other models have an electronic or mechanical indicator.

Yes

High efficiency particulate air (HEPA) filter
High efficiency particulate air (HEPA) filterHigh-efficiency particulate-air (HEPA) filters provide the highest level of vacuum-cleaner filtration. In our tests, models with a HEPA filter have been very effective at reducing emissions. However, some models that don't have HEPA filters have performed just as well in our emissions tests, and such vacuums may cost less than HEPA models.

Self-propelled
Self-propelledThis feature typically uses a transmission and drive system to assist the pushing and pulling of the vacuum, thereby requiring little effort by the user. This feature, however, typically adds weight that can make some vacuums very heavy and difficult to carry or use on stairs.

No

Specs

Bag
BagDenotes whether the model has a disposable waste bag. A growing number of vacuums, particularly upright models, use a container that can be emptied, eliminating the bag. To capture fine-dirt particles, however, these models must use a filter (such as a HEPA filter) that can need regular cleaning, or replacement. Replacement filters tend to be significantly more expensive than bags. While vacuums with bags may also use filters, the bag acts as a pre-filter that helps to keep the fine-dirt filter cleaner, thus extending its performance until cleaning or replacement. Another caveat: Emptying the dustbin and cleaning a filter can be messy, and handling it may expose you to dust and other allergens.

No

Weight
(lbs.)
WeightThe weight of the vacuum cleaner, to the nearest pound. If you expect to carry your vacuum up and down stairs, consider a lighter vacuum (under 20 pounds).

14

Cord length
(ft)
Cord lengthThe length, in feet, of a model's power cord.
